Voice assistants are increasingly powered by large language models. If you want to bring Anthropicโs Claude API into an Alexa skill you maintain or build, this guide walks you through the practical architecture, concrete code patterns, and operational considerations youโll need โ from quick proof-of-concept to a production-grade skill.

Both Gemini 3 Pro (Google/DeepMind) and Claude Sonnet 4.5 (Anthropic) are 2025-era flagship models optimized for agentic, long-horizon, tool-using workflows โ

OpenAIโs GPT-5.1 is an incremental but product-focused update that introduces two usage-flavored variants (Instant and Thinking), extended prompt caching, and

With the October 2025 arrival of Claude Haiku 4.5, Anthropic delivered a model explicitly optimized for agentic workloads: fast, cost-efficient, and tuned for sub-agent orchestration and โcomputer useโ tasks (i.e., driving tools, editors, CLIs).

Anthropicโs Claude Sonnet 4.5 (often shortened to Sonnet 4.5) arrived as a performance-focused successor in Anthropicโs Claude family. For teams deciding

Anthropicโs Claude Sonnet 4.5 arrived as a focused update for coding, agentic workflows, and โcomputer useโ โ the kinds of tasks that require long context,

Anthropicโs Claude Sonnet 4.5 is a 2025 update focused on long-duration autonomous work, stronger tool/computer use, tighter safety/alignment, and richer developer features (context editing, memory, in-chat code execution and file creation). Benchmarks and vendor tests emphasize large gains on coding and โagenticโ tasks (e.g., Anthropic reports ~30 hours of continuous autonomous coding in internal tests and big jumps on OS/tool-use benchmarks).

Claude Sonnet 4.5 (commonly shorted to Claude 4.5) is Anthropicโs September 29, 2025 frontier release focused on long-horizon agentic work, coding, and
